many to many relationships

Hi to all,I want to know, if it is possible to model a many to many relationship with cards or properties?The only possibility I have found is the abibility to model a one to many card relationship by using a card tree. For properties I have found nothing, because there is obviously no multi-select list available. Our actual approach to model a many2many relationship is by using tags which is not really comfortable.

What we want to model is the relationship between our customers and our stories. We want to report: "Show me all stories for this customer" and "Show me all customers for this story". Is there a way to model this?/Rainer

We do not have a way to special way to manage many to many relationship but you can create card relationship properties that can link cards to each other without the need for a tree. Using these you will not be able to set multiple values for a single property but you could create multiple properties, such as "Customer 1", "Customer 2" etc... on each card. You will be able to create tables or charts that show these relationships. For example:

"Show me all stories for this customer"

{{ table query: SELECT name, number WHERE "customer 1" is THIS CARD or "customer 2" is THIS CARD}}

I hope this information will be useful.

For your information we use tags to manage our customer to story links and we have found this to be adequate. I'd be interested in understanding what about this is uncomfortable for you?

thanks for your answer, but I think working with card relationship properties to model a many to many relationship is not the way I want to go.

About your question. Working with tags is not really uncomfortable, tagging is a nice feature, but to use it to model a many to many relationship (like customer to story and vica versa) is for me a kind of wrong usage, because a tag is a tag and should not have a specific build in logic. A customer should be an object (card typ) with the possibility to model a many to many relationship with any other object (card typ). A tag is not the same, its only a workaround.

It is planned to add many to many relationships in a further release of mingle?
